Wrapping the Simple Theme

The xhtml theme uses the "wrapping" technique described by Extending Themes. Let's look at how the HTML tags are wrapped by a standard header and footer. For example, in the textfield template, text.ftl, the controlheader.ftl and controlfooter.ftl templates are wrapped around the simple template.

CSS XHTML theme header

The header used by the HTML tags in the css_xhtml theme is complicated. Unlike the xhtml theme, the CSS theme does not use a labelposition attribute. Instead, the label position is defined by CSS rules.

Note that the fieldErrors, usually caused by Validation, are displayed in a div block before the element is displayed.

CSS XHTML theme footer

And the controlfooter.ftl contents:

Special Interest

Two css_xhtml templates of special interest are head and form.

Head template

The css_xhtml head template is similar to the xhtml head template. The difference is that CSS is used to provide the layout.

The head includes a style sheet.

Form template

The css_xhtml form template is almost exactly like the xhtml form template, including support for Pure JavaScript Client Side Validation. The difference is that instead of printing out an opening and closing <table> element, there are no elements. Instead, the CSS rules for the individual HTML tags are assumed to handle all display logic. However, as noted, client-side validation is still supported.
